let assert = require('assert');

//
// New function to require a module
// and handle require errors
//
// Input: module name or path
// Output: module content, like "require()"
//
function requireModule (modulePath) {
  assert.equal(typeof (modulePath), 'string', 'Argument "modulePath" must be a string.');
  try {
    return require(modulePath);
  } catch (error) {
    if (error.code !== 'MODULE_NOT_FOUND') {
      throw error;
    } else {
      console.error('Module "' + modulePath + '" not found. Maybe it is not installed yet?');
    }
  }
}

// Test to require an unknown module
let moduleNotFound = requireModule('moduleNotFound');
